The aim of this study was to illuminate the pattern of confusional episodes with regard to the content of elderly patients' actions and speech. Fifty-one (11.2%) out of 457 people admitted to an orthopaedic clinic developed acute confusional state. Non-participant direct observations and daily clinical bedside follow-up observations were made during the confusional episodes, focusing on the patien

BACKGROUND: Central venous oxygen saturation (ScvO2) and oxygen tension (PcvO2), obtained from the superior vena cava, correlate well with mixed venous (pulmonary arterial) oxygen saturation (SvO2) and tension (pvO2) when the hematocrit is normal. The present study was undertaken to assess whether extreme hemodilution affects this relation. METHODS: We compared mixed and central venous blood durin

In this study the effect of different times of exposure to ethanol (1-7 days, 100 mM) on bradykinin and GTP(S)-stimulated activation of phospholipase C in NG 108-15 cells and on the binding of [3H]bradykinin to its receptors was investigated. Ethanol attenuated both agonist and GTP-analogue-induced hydrolysis of phosphoinositides for a period of up to 4 days of treatment, while exerting no effect

The 7-10 November 2004 period contains two events for which the local ground magnetic field was severely disturbed and simultaneously, the solar wind displayed several shocks and negative B-z periods. Using empirical models the 10-min RMS Delta X and Delta Y at Brorfelde (BFE, 11.67 degrees E, 55.63 degrees N), Denmark, are predicted. The models are recurrent neural networks with 10-min solar wind

The essential protein Cdc13p binds the single-stranded telomeric 3' overhangs in Saccharomyces cerevisiae and takes part in the regulation of telomere length. The DNA-binding domain (DBD) of Cdc13p is structurally established by an oligonucleotide/oligosaccharide-binding (OB)-fold domain. The sequence homolog in Saccharomyces castellii (scasCDC13) was characterized previously, and the full-length

The anaphylatoxic peptide C3a is a pro-inflammatory mediator generated during complement activation, whose specific G protein coupled receptor is expressed on granulocytes, monocytes, mast cells, activated lymphocytes, and in the nervous tissue. We have generated RBL-2H3 cell clones stably expressing mutants of the human C3a-receptor (C3aR) with combined alanine (Ala) substitutions of ten C-termin

OBJECTIVE AND DESIGN: To correlate the changes in periarticular tissue levels of pro-inflammatory cytokines and endothelin-1 (ET-1) to local pathophysiology in rats with antigen-induced arthritis (AIA). MATERIALS: The periarticular soft tissue was excised from sixty-six rats at different stages of AIA. METHODS: The samples were homogenized and the levels of immune like (LI) reactivities were deter

We reconstruct the Holocene range fluctuations of the European pond turtle (Emys orbicularis) for northern and Central Europe. Based on 529 subfossil records and radiocarbon dating of critical finds, we provide evidence that E. orbicularis experienced a rapid range expansion with Holocene warming. Phylogeographic data argue for a colonization of northern and Central Europe from a glacial refuge lo

Age at menarche is a strong and consistent predictor of breast cancer risk in the general population, but has not been well studied in women with a family history of breast cancer. We conducted this study to examine whether the presence of a deleterious BRCA1 or BRCA2 mutation influences age at menarche and to investigate whether or not there is an association between age at menarche and the risk

The Kidd (JK) blood group system is clinically important in transfusion medicine. Alloantibodies to antigens in this system may be produced following blood transfusion or during pregnancy and can result in serious haemolytic transfusion reactions and haemolytic disease of the newborn (HDN). JK antigens on erythrocytes are carried by glycoproteins with the capacity to transport urea through cell me

The inherent limitations of a specific pencil beam model have been studied when applied to a cylindrical geometry simulating the neck region. A comparison is made between measured and calculated absorbed dose in a cylindrical phantom. The goal is to quantify the deviations in the absorbed dose level, i.e., the dose per monitor unit, when photons are used for the treatment of head and neck tumours.

Purpose: A considerable fraction (30% to 70%) of families with verified or putative hereditary nonpolyposis colorectal cancer fails to show mutations in DNA mismatch repair (MMR) genes. Our purpose was to address the genetic etiology of such families. Materials and Methods: We scrutinized a population-based cohort of 26 families from Finland that had screened mutation-negative by previous techniqu
